ROLL OF PAPER FOR USE IN COPYING-MACHINES.

Specification of Letters Patent.

Patented Jan. 20,1914.

Application filed January 4, 1911. Serial No. 600,702.

To all whom it may concern:

Be it known that I, AUGUs'rUs DAVID KLA- BER, a subject of Great Britain, residing at London, England, have invented new and useful Improvements in Rolls of Paper for Use in Copying-Machines, of which the following is a specification.

This invention relates to improvements in rolls of copying paper such as are em ployed. upon machines for press copying letters.

Vith rolls of paper for this purpose as at present constructed, it is found that despite the fact that the paper itself is treated with some hygroscopic substance or liquid, that there is a tendency when the paper is kept for any considerable length of time in a dry atmosphere, for the said paper to become too dry for use. Attempts have been made to overcome this disadavantage by placing a humidifier in the case containing the roll of paper. It is found, however, that even with this provision there is still a tendency for the paper to become too dry. Again, the

provision of a humidifier such as that just above referred to does not meet the case when the roll is held in stock for a considerable time before u'se.

It is the object of the present invention to provide a means designed to overcome this disadvantage, and with this object in view I construct and arrange the hollow core of the roll in a manner such that it may form a receptacle for some more or less absorbent material which is charged with moisture so that air passing therethro-ugh is moistened and the paper thus kept in a moistened atmosphere which keeps it in a fit state for use. In order to permit the more ready passage of moistened air to the paper, the aforesaid hollow core upon which the paper is coiled may be perforated.

In carrying the invention into effect, I employ a metal or other body which may be hollow and of square, triangular, polygonal or of any other suitable cross sectional outline and which body fits with a certain amount of tightness within the aforesaid hollow core of the roll. The spaces between the outside of the aforesaid body and the inside of the core form receptacles which are more or less closely packed or filled with the moisture charged material. The roll may be mounted in the receptacles in the machine by any suitable means which may consist of suitably shaped plugs, which are revolubly supported by the ends of the receptacle and which plugs are suitably shaped to fit with- 111 or otherwise engage the ends of the hollow or other body, or a spindle may be passed therethrough.

In order that the invention may be better understood, drawings are appended in which Figure 1 is a part sectional elevation showing a roll embodying a form of the present invention, mounted within a con tamer. Fig. 2 is a transverse sectional view thereof. Fig. 3 is an end view showing a modified form of inner hollow body. Fig.

at is a similar view showing a further modification. Figs. 5 and 6 are similar. views showing further modifications.

Referring to the appended drawings a Fig. 1 indicates a container for the roll which is mounted upon the frame of the copying machine and which is provided witha hinged cover it. The case is shown provided with a'humidifier b, but obviously this can be dispensed with if desired and the moistened material or the roll itself, relied upon to keep the air in and around the roller moist. The paper is wound upon a hollow core 0 of ordinary form except that as shown in Fig. 1 it may be provided with a number of perforations to permit the more ready access of the moistened air to the paper. Fitting more or less tightly within the hollow core just referred to is another body 62 which is also hollow and which body of triangular section so that there is provided between it and the surrounding core 0 a number of longitudinal spaces 6. The spaces just referred to are packed with some suitable absorbent material indicated by f which is charged with moisture. Instead of a triangular cross section, the hollow body 0? may present any other desired cross sectional outline such as for instance as a regular polygonal outline as shown in Fig. 3, or square as shown in Fig. 4:. Again, in stead of a hollow body, a body such as shown in Fig. 5 may be employed, or instead of this, a hollow body provided wit-h radial longitudinal projections such as al Fig. 6. In this case the absorbent material is placed on th exterior of the part d. The hollow member 02 may also be perforated if desired so that the damp air has more ready access to the inner convolutions of the aper. It will however, be readily understood that the shape of the inner body 05 may be varied at will so long as there are provided the necessary longitudinal spaces to contain the absorbent body. The roll may be revolubly mounted in its case by means of suit-ably shaped projections which may be attached to the milled heads 9 and which enter the ends of the said hollow bodies and rot-ate therewith as the paper is drawn off. The paper passes out of the container through a slot 2' which is provided between the edge of the cover it and the body portion of the container a. Any other means of mounting the roll may however, be employed.

Claims.

1. In a roll of copying paper, a hollow core, moisture charged material therein and means within said core adapted to retain the material charged with moisture, said means forming an air passage through said core whereby the roll of paper will be surrounded by a humid atmosphere, and a closed outer container for the roll.

2. In a roll of copying paper, a hollow perforated core, moisture charged material therein and means within said core adapted to retain the material charged with moisture, said means forming an air passage through said core whereby the roll of paper will be surrounded by a humid atmosphere, and a closed outer container for the roll.

3. In a roll of copying paper, a hollow perforated core, moisture charged material therein, means within said core adapted to retain the material charged with moisture, said means comprising a body fitting within the core, the moisture charged material being placed between the inner circumference of the hollow core and the periphery of the inner body, said means forming an air passage through said core whereby the roll of paper will be surrounded by a humid atmosphere, and a closed outer container for the roll.

4. In a roll of copying paper, a hollow perforated core, moisture charged material therein and means within said core adapted to retain the material charged wit-h moisture, said means comprising a hollow body having a polygonal cross section so that receptacles are formed between its outer circumference and the inner circumference of the perforated core for the moisture charged material, said means forming an air passage through said core whereby the roll of paper will be surrounded by a humid atmosphere, and a closed outer container for the roll.

5. In a roll of copying paper, a hollow perforated core, moisture charged material therein and means within said core adapted to retain the material charged with moisture, said means comprising a hollow perforated body having a polygonal cross section so that receptacles are formed between its outer circumference and the inner circumference of the perforated core for the moisture charged material, said means forming an air passage through said core whereby the roll of paper will be surrounded by a humid atmosphere, and a closed outer container for 'the roll.

6. In a roll of copying paper, a hollow perforated core, moisture charged material therein and means within said core adapted to retain the material charged with moisture, said means comprising a hollow body of such form that there are formed between it and the inner circumference of the core, a plurality of spaces adapted to contain a moisture charged material, said means forming an air passage through said core whereby the roll of paper will be surrounded by a humid atmosphere, and a closed outer container for the roll.

7. In a roll of copying paper, a hollow perforated core, moisture charged material therein and means within said core adapted.

to retain the material charged with moisture, said means comprising a hollow perforated body of such form that there are formed between it and the inner circumfer ence of the core a plurality of spaces adapted to contain a moisture charged material, said means forming an air passage through said core whereby the roll of paper will be surrounded by a humid atmosphere, and a closed outer ontainer for the roll.
